In Latin, there are prepositions that may be followed by a noun in accusative (like ad), ablative (cum) or both (in).
I once thought ope was a preposition to be used with genitive, which I found pretty interesting because most Latin grammars do not mention it (I think I once read one that did, but I can't find it now). Then I realized it is just the dative of ops (in my defense, ope -by the power or support of sth- has a very preposition-ish meaning). Nevertheless, doing some linguistics-fiction I wondered it was a feasible way for such a preposition to evolve after the desappearence of other uses of ops.
And then I found this site, stating that there is the preposition tenus, which actually works with genitive. I've never heard of that one, and the page does not cite any sources, but there are other sources that favor the point.
My Latin is mostly ecclesiastical, so I am more or less ignorant of many classical- and medieval-specific features.
My question is: were prepositions/adpositions with genitive a real thing at any point in Latin history? Is there more than one such adposition?
Update: some people have pointed that tenus is indeed a postposition, since it goes after the noun being modified. In the meantime, I have learnt that in linguistics there is a more general word, adposition to embrace both pre- and postpositions. I was unaware of any of these two words: good to learn new things. Thanks @Cerberus.
I added the concept to the question's title. I left the word preposition here and there for a number of reasons: 1) both sources cited treat tenus as a preposition (even clarifying it has to be used after the noun), 2) there is no adposition
tag in Latin.SE, 3) in English, prepositions may be used after nouns in certain circumstances (see here, under the title Usage Note), and some definitions confirm it.
